Primary Examiner-Bernard Konick Assistant ExaminerSteven B. Pokotilow Attorney-Robert G. Clay ABSTRACT: A method and apparatusis provided for recording and reproducing television or other broad band signals with an altered time base effect so as to provide, for example, in the case of television signals, slow motion, faster than normal motion, stop motion or reverse motion. To provide slow motion replay of television signals, successive fields of the signal are recorded separately on a plurality of magnetic mediums, and at predetermined head-to-medium writing speeds, and are played back at substantially the same head-to-medium writing speeds. On playback, each field is repeated a number of times depending upon the time base effect desired. Reverse motion is provided by reversing the order of replay of the fields.
